iCloud Mail not syncing across devices

I agree. I have reverted to using Gmail on my phone instead of Apple mail. Gmail syncs perfectly with Apple Mail on the Mac, so the problem is clearly with the iPhone Mail app. Apple is losing my support. I have changed to Google Chrome and Gmail from Safari and Mail, which have served me well for many years until last month. The problem is with Apple.

Same issue. No resolve (or when I do, the problem returns).

I receive over a hundred or more [legitimate] emails a day. I check my phone dozens of times a day, moving messages to specific folders, flagging, reading and replying. I RELY ON APPLE TO KEEP THIS IN SYNC. Now I'm left with a quandary: wait to read and sort messages in macOS, read and sort messages in iOS, or painstakingly try to manually keep both in sync.

I fixed this problem updating to the latest macOS two weeks ago. Last week I encountered problems again that persist to this day.

There is no reliable solution (signing in/out, updating, turning off/on) and Apple's integrity in the matter is at stake. I am trying to run a business and manage critically ill patients. Apple, this is maddening.

For God's sake, Apple - I even have problems notifying you about problems. After 15 minutes, I'm back here again trying to convey what I tried to update:

Mysteriously (without any intervention) my mail is syncing better. This is the second time in a month it's been grossly off, then almost back to normal. I have no faith this has been resolved as I've had too many serious issues lately and Apple seems more and more unreliable.

1️⃣ The first [possible] resolution came by way upgrading to macOS 10.15.6. Problem resolved itself shortly thereafter (later, re-presenting). A legacy Mac user, I am gun shy about initiating updates. I see little benefit these days in new releases; more frustrated with features that are taken away.

2️⃣ The second [possible] resolution came by way of restoring my MBP to power 24/7. I eliminate standby mode completely, only reducing brightness or turning off the monitor (docking station or laptop). The goal is to use my desktop as the primary mail authority (reading, moving, deleting, sending) and let it push to the server and down to mobile devices. By leaving it running, there's no reason why is shouldn't be processing in real-time.

Mail seems to be frequently hung "moving messages." It's also not uncommon to see the status bar (bottom left) waiting to process income or outgoing messages. The past few weeks, I'll receive an error dialog that it failed to move a particular message to a mail box. 🙄

Apple, I try to be a highly organized and efficient professional. You royally make a mess of people's lives when basic, fundamental processes stop working properly.

Couldn't have said it better - thank you!

On a side note, I also see little benefit in new releases, and have not updated my Mac to Catalina for many of the same reasons, (in particular because I'll lose access to some programs that will no longer run, like Picasa).

It's unfortunate that when you contact support about any issue they tend to resort to the standby reply - it's because you haven't updated to the latest version of software.

This should have nothing to do with the functionality of syncing mail or anything else as simple as that.

I've been using iCloud Mail for years now. I have an iMac, iPad and iPhone 11 Pro. About 3 weeks or so ago, my email stopped syncing. All devices receive the emails, however; when I delete or read emails on my iPhone, this doesn't sync with my other devices. I haven't made any changes to my accounts to cause this, so I am at a loss. I've tried signing out of iCloud on all my devices and then logging back in, to no avail. If I go to iCloud.com and read/delete emails, then my devices will update.

Please help!!

Keith, actually I am really surprise that it has been syncing for you before.. I have been using iCloud email for 3 years and never synced the read, deleted or moved emailed across all devices!!!

This is a serious issue Apple needs to look at.

I’m the same Keith - mine literally stopped syncing 2 weeks ago. Use it on iPad / iPhone / MacBook Air, now it only syncs from MacBook Air. like you I didn’t do anything. It has always synced for me for years!! Very frustrating, I hadn’t updated. Will our request in tk Apple and see what they say

We pay for extra iCloud storage like lots of people do, I’m sure. It’s bigger than mail. NO NOTIFICATIONS sync. FaceTime, Reminders and notes don’t sync across my devices. Neither do notifications from third party apps. This was never a problem in the past. It’s definitely a server level issue.

UPDATE: please accept my apology, I think it only worked because I have been using Apple Smart Case which is charging the iPhone constantly so no wonder why it work. Now I have taken the smart case off, I am back to SQUARE ONE. All I can say, I hope Apple listen to this and find a solution.

Thank you. That is very helpful.. I gave up and switched to Spark. I had intended to standardise on Apple Mail with the ***** Mailsuite. I will try again if your solution persists. Why should we have to put up with this. This is the very essence of Apple Mail. I think we need to ensure that every change, or update to Apple Mail is very quickly tested for synchronisation. That must be helpful to both the community and to Apple. I can’t say I am looking forward to switching back!

Keith.

Right - this is similar to me keeping my MBP running without going into standby mode. As long as there is a device constantly pinging and managing, syncing seems to work. Why the **** the servers don't seem to manage this is beyond me.

Thanks for the update! I tried this, and alas, no avail! I'm curious if this was an iCloud issue for you or do you use Gmail? Mine is not syncing Gmail. I'm having to use webmail now so that I can keep my account synced between devices and I hate it! :)

I have the same issue, but it didn’t start till after the the iOS 14 update. I have an older iMac, an iPad Pro, and an iPhone 8. I logged out of iCloud and logged back in on all devices but the iPad is the one that never seems to catch up.

Rebuild got the mailbox in sync. But then it didnt' stay synced up afterwards. It was like the sync info gets to my MacBook but doesn't make it to the Mail program.

My issue is similar to many here, looking for clues before I poke around some more.

I have signed out of iCloud and still all Mail edits (mostly deleting and marking as 'read') made on my Mac do not show up on my iPhone. So on my Mac, I have reviewed all my mail and have no new mail yet my phone and my iPad say I have 572 emails that I haven't read.
